## Abstract In this paper it is shown that the charge transfer kinetics of the oxidation of sodium dithionite at a gold electrode in alkaline solution can be increased by modifying this electrode with cobalt(II)tetrasulfonated phthalocyanine, sodium salt (CoTSPc) or 5,10,15,20‐tetrakis‐(4‐sulfonato

In SERS-active systems, when a free base porphyrin is adsorbed at a roughened metal surface, the metal ion may be incorporated into the porphyrin core. We have investigated the metalation kinetics of 5,10,15,20-tetrakis(1methyl-4-pyridyl)porphyrin (TMPyP), reÑected in the time evolution of its SERRS
